24 Jul Core Industries Index (ICI) Gets a Major Upgrade: What It Means for India’s Economy
Why in News?
The Index of Core Industries (ICI) has been revised with a new base year (2022–23 = 100), updated methodology, revised sectoral weights, and the inclusion of iron ore as the ninth core industry. The revised series aligns the ICI with other recently updated macroeconomic indicators such as the Wholesale Price Index (WPI), Consumer Price Index (CPI), Index of Industrial Production (IIP), and National Accounts.
The June 2026 data under the new series also recorded 5% growth, indicating resilience in industrial activity despite global geopolitical uncertainties and supply chain disruptions.

The Index of Core Industries (ICI) measures the performance of industries that serve as the backbone of India’s industrial economy.
These sectors supply essential raw materials and energy required for manufacturing, infrastructure, and economic growth.
Since core industries account for a significant share of industrial production, the index serves as an early indicator of economic activity.
What Has Changed in the New ICI Series?
The revised Index introduces several important improvements.
New Base Year
The base year has been updated to 2022–23 = 100, replacing the earlier series.
Updating the base year ensures that the index reflects the current structure of the economy and changing production patterns.
Addition of Iron Ore
For the first time, iron ore has been included as a separate core industry.
Consequently, the number of core industries has increased from eight to nine.
This addition better captures India’s expanding steel and mining sector.
Revised Sectoral Weights
The weight assigned to each sector has been recalculated to reflect current economic realities.
Some important changes include:
| Sector | Change |
|---|---|
| Electricity | Weight increased to over 30% |
| Coal | Weight reduced |
| Natural Gas | Weight reduced |
| Iron Ore | Newly included |
These revisions acknowledge the growing importance of electricity and renewable energy in India’s economy.
Nine Core Industries
| Core Industry | Importance |
|---|---|
| Coal | Energy security |
| Crude Oil | Petroleum production |
| Natural Gas | Fuel and fertilizers |
| Refinery Products | Energy supply |
| Fertilizers | Agriculture |
| Steel | Infrastructure and manufacturing |
| Cement | Construction sector |
| Electricity | Industrial and household consumption |
| Iron Ore | Raw material for steel production |
Together, these industries account for about 40% of the weight in the Index of Industrial Production (IIP).
Why Is the ICI Important?
Early Indicator of Industrial Growth
The Index is released before the IIP and provides an early picture of industrial performance.
Therefore, policymakers and investors closely monitor monthly ICI data.
Supports Economic Planning
Government agencies use the Index to assess:
- Industrial production
- Infrastructure activity
- Energy demand
- Manufacturing trends
As a result, it plays an important role in economic policymaking.
Helps Investors
Strong growth in core industries often signals improvement in manufacturing and infrastructure.
Meanwhile, weak performance may indicate slowing economic momentum.
Significance of the Revision
Better Representation of the Economy
Economic structures evolve over time.
Industries such as electricity and mining have expanded significantly during the last decade.
Updating the index ensures that official statistics remain relevant.
Improved Statistical Accuracy
The revised methodology reduces double counting in sectors such as steel and coal.
Consequently, the data provide a more reliable picture of industrial output.
Alignment with Other Economic Indicators
India has recently updated several important macroeconomic datasets.
These include:
- Gross Domestic Product (GDP)
- Consumer Price Index (CPI)
- Wholesale Price Index (WPI)
- Index of Industrial Production (IIP)
The revised ICI completes this broader modernization of India’s statistical system.
June 2026 Performance: What Does It Indicate?
The revised data showed 5% year-on-year growth in June 2026.
Strong performance was observed in:
- Iron ore
- Electricity generation
However, analysts caution that part of this growth reflects a base effect, as production was comparatively lower during the corresponding period of the previous year.
Therefore, sustained growth over the coming months will provide a clearer picture of industrial recovery.
Challenges Facing Core Industries
Declining Domestic Production
Production of crude oil and natural gas has remained under pressure in recent years.
Lower domestic output increases India’s dependence on imports and affects energy security.
Global Geopolitical Risks
Conflicts in West Asia and disruptions in global shipping routes can increase input costs for industries.
Moreover, supply chain uncertainties may affect industrial production.
Energy Transition
India is rapidly expanding renewable energy capacity.
Nevertheless, balancing traditional fossil fuels with clean energy remains a policy challenge.
Government Initiatives Supporting Industrial Growth
Several flagship initiatives aim to strengthen industrial output:
- Make in India
- PM Gati Shakti National Master Plan
- National Infrastructure Pipeline (NIP)
- Production Linked Incentive (PLI) Scheme
- National Logistics Policy
- National Green Hydrogen Mission
Together, these initiatives seek to improve competitiveness and reduce production costs.
Way Forward
Strengthen Domestic Resource Production
Increasing exploration of crude oil and natural gas can reduce import dependence.
Improve Statistical Systems
Regular revision of base years and methodologies should continue to ensure reliable economic indicators.
Accelerate Infrastructure Development
Investments in transport, power, logistics, and digital infrastructure will support sustained industrial growth.
Promote Clean Energy
Expanding renewable energy while improving grid efficiency can strengthen long-term energy security.
Prelims Practice Questions
Q1. With reference to the Index of Core Industries (ICI), consider the following statements:
- The Index is compiled by the Ministry of Commerce and Industry.
- The revised series has 2022–23 as its base year.
- Iron ore has been included as the ninth core industry in the revised series.
Which of the statements given above is/are correct?
(a) 2 and 3 only
(b) 1 and 2 only
(c) 1 and 3 only
(d) 1, 2 and 3
Answer:
(a) 2 and 3 only
Explanation
- Statement 1 is incorrect. The Index of Core Industries is compiled by the Office of the Economic Adviser, Department for Promotion of Industry and Internal Trade (DPIIT), Ministry of Commerce and Industry, while many macroeconomic statistics are released by MoSPI. UPSC often tests such institutional distinctions.
- Statement 2 is correct. The revised ICI series uses 2022–23 as the base year.
- Statement 3 is correct. Iron ore has been added as the ninth core industry.
Q2. Which of the following are included in the revised Index of Core Industries?
- Steel
- Cement
- Electricity
- Iron Ore
- Automobiles
Select the correct answer using the code below.
(a) 1, 2 and 3 only
(b) 1, 2, 3 and 4 only
(c) 2, 3, 4 and 5 only
(d) 1, 2, 3, 4 and 5
Answer:
(b) 1, 2, 3 and 4 only
Explanation
The revised ICI covers nine core industries: Coal, Crude Oil, Natural Gas, Refinery Products, Fertilizers, Steel, Cement, Electricity, and Iron Ore. Automobiles are not part of the Core Industries Index; their performance is reflected through other industrial indicators.
